Derin was born in 1994, and started riding ponies when he was only 4-years-old – at the Galatasaray Pony Club in Istanbul, Turkey. He has been passionate about riding ever since.
When he was 10-years-old, Derin started competing with horses in the children’s category in Turkey. When he reached the age of 12, he got selected for the Turkish Children’s Team and started representing his country in international competitions.
In the beginning of 2012, Derin moved from Turkey to train with Bert Romp and Jos Lansink. In April 2012, Derin started training with Henk Nooren and moved with his horses to Nooren's Stables in Belgium before he ventured out on his own in 2016 and moved his horses close to Maastricht, Netherlands. Derin now manages his own stables, and trains with Jos Lansink.
Besides being a successful showjumper, Derin has also been pursuing his studies at Maastricht University since September 2012 and got his degree in International Business with a major in Finance in 2015.
At the beginning of 2017, Derin also graduated from the Young Riders Academy-team of 2016 – after participating a year in the educational program.
His current top horses are Harry K, Dadjak Ter Puttenen, Narazo de Nyze Z, Je Suis Van De Bien and Flaming Key Z. With Harry K, Derin won the 2017 CSIO3* Grand Prix of Drammen as well as the 2016 CSI4* FEI World Cup of Doha. The pair was also on the winning Turkish Nations Cup team at CSIO3* Sopot back in 2014.
